Topic for May 14 -- User interface of mobile devices

The uniqueness of mobile devices... beyond multi-touch screen, accerlermeters, voice, and haptic

First of all, mobile device is by far a very personal device, one can enjoy his own stuff on his own. He might not want to share it, and it will actually be very hard for him to share with even anybody standing around him. The future interface of mobile devices would be very easy to switch between private mode, and public mode. When it is private, strictly nobody but the user can see/hear/feel/control the content. When it is public, others that the user chooses would be able to see/hear/feel/control the content, whether a laser projection, a beam of sound/video, virtual reality artifacts etc...

The hybrid of virtual and reality. We will soon see the convergence of the virtual world and real world. Virtual objects would spread everywhere in our real everyday life. We will be able physically interact with those virtual objects as if we open a door, kick a football and pick up a phone. the virtual objects would give us physical feedback so that we can see/hear/feel. Of course, they are not limited by physical laws. We can bring a virtual object by swing one of our fingers. We can open a virtual door by just thinking of it.

Mind interaction -- the ultimate human-machine interaction.
